What is the key indication for using hyperbaric oxygen therapy?

Hyperbaric oxygen therapy (HBOT) is primarily indicated for decompression sickness, which occurs when a diver ascends too quickly from deep waters, causing nitrogen bubbles to form in the bloodstream and tissues. This condition can lead to serious complications, such as joint pain, neurological issues, and potentially life-threatening situations. HBOT works by delivering pure oxygen to the patient in a pressurized environment, allowing the nitrogen bubbles to dissolve more rapidly and reducing the risk of damage to tissues.

While other conditions are associated with respiratory issues, such as chronic obstructive pulmonary disease, severe asthma attacks, and sleep apnea, they do not involve the same acute physiological effects that decompression sickness does and are not standard indications for HBOT. Thus, the effective application of hyperbaric oxygen therapy is most clearly demonstrated in cases of decompression sickness.
